SPECIFICATION forming par-tof Letters Patent No. 638,144, dated November 28, 1899.

Original application filed December 22,1898, Serial No. 700,020. Divided and thisapplication filed March ZO, 1899. Serial No. 709,708. (No model.)

T0 ctZZ whom it may concern:

Be it known that I, ISAAC E. REIS, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Water-Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specication.

My invention relates to an improvement in an apparatus for heating Water by the use of gas or other vapor, the device belonging to that class of heaters in which the water is heated as it Iiows continuously through vthe apparatus, such as described in my application led December 22, 1898, Serial No. 700,020, of which this application is a division.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a vertical sectional View of my improved heater, taken on line I I, Fig. II. Fig. II is a horizontal sectional View taken on line II II, Fig. I. Fig. III is a perspective View of the coil separated from the heater.

1 designates the burner of the heater, having slits in its surface for the escape of gas or vapor, which enters through a supply-pipe 2 and a mixing-chamber 3, within which the gas or vapor to be consumed is mixed with oxygen. The burner is formed with a iiangerim 4, provided With an upturned edge 5, the said flange formingthe base of the heater and being supported on legs 6.

7 designates an outer casing or jacket mounted on the angerim 4; and confined Within the upturned edge 5 of said rim. The casing or jacket 7 is of box-like form and is provided at its lower portion With perforations 8, through which fresh air may be con stantly admitted to the interior of the heater to provide for perfect combustion of the gas In the top of the casing or jacket 7 are perforations 9, through which surplus heat is permitted to escape.

10 designates an inner casing situated Within the outer casing, but separated therefrom to provide an air-space 11 between the two casings. The inner casing 10 is open at top and bottom, and its lower end occupies a position some distance above the burner 1, the casing being preferably supported upon standards 12, fixed to the base or iiange rim of the burner. The perforations 8 in the outer casing or jacket occupy a position beneath the bottom line of the inner casing, so that the air entering through said perforations passes into the interiorof both casings.

13 designates a water-supply pipe provided with a faucet-valve 14e, by which the iow of water through said pipe may be regulated to a nicety on opening the valve more or less. The supply-pipe 18 communicates with a coil 15, arranged in a vertical series of horizontal spirals within the casing 10, the said coil be ing suitably supported above the burner 1. The pipe of the coil 15 extends from the sup= ply-pipe 13 upwardly into the casing 10 to a point 16 (see Fig. I) and is then bent back and forth in spiral form into a vertical series of horizontal spirals, as shown, and, descending, as shown at 17, Fig. I, joins at 18 with a discharge-pipe 19, either end of which may be used as the out-let from said pipe, while the other end is closed by a cap 20.

In the practical use of the apparatus the heat from the burner rises within the casing and comes in contact with the coil, which being wound in spiral form, as clearly shown in Fig. II, and being arranged in a vertical se ries of horizontal spirals, as shown in Fig. I, presents a very compact and large amount of heating-surface, so that the Water flowing continuously through the said coil becomes thoroughly heated, the surplus heat finding egress through the perforated top of the outer casing or jacket 7, and thereby permitting a continuous circulation of air through the heater and a consequent inflow of fresh air through the perforations S to supply the nec'- essary amount of oxygen for the perfect con; sumption of the vapor.

By thus constructing a Water-heater provi sion is made for an inexpensive and effective apparatus for heating Water as it flows continuously from a source of supply to the point where it is discharged for use...

I claim as my invention-'- l. In a Water-heater, the combination of a spiral being connected spirally and theuspisource of heat, anda Water-pipe formed into ials being connected at their ends; substana Vertical series of horizontal spirals, subtially as and for the purposes set forth.
